1.2 Optional Components
Options for the SmartWireless® CX Sensor Station are as follows:
strobe
horn
external ‘Wet’ or ‘Dry’ alarm port
1.3 Alarms and Fault Condition
The CX Sensor Station includes an optional strobe and/or a piezoelectric horn and an external alarm
connector. The strobe is associated with Alarm 1, the horn is associated with Alarm2 and the external alarm
connector utilizes all alarm outputs (alarm 1, 2, 3 and fault) for connection to external alarm devices. The
external alarm outputs can be used to control annunciating devices or as signal inputs to other control
devices. The CX permits alarm and fault conditions to cause an assigned relay to fire, triggering external
alarm devices. When the alarm level is reached either the devices mounted to the box or attached to the
external alarm connector are activated, or both. The assigned relay outputs will return to normal state when
a gas alarm or a fault condition clears. The Alarm Relay Output can be either ‘Wet’ or ‘Dry’ determined

1.5 Radio Module
The SmartWireless® CX offers a wireless option to connect it to the SmartWireless CXT and other devices
wirelessly. The Radio Module includes a transceiver that operates at 2.4GHz and conforms to non-licensed
radio frequency usage worldwide. Spread spectrum technology supports integrity and security for the
wireless network.
The SmartWireless CXT and CX products use a wireless network with a mesh topology. If radio
communication directly between two devices is impossible due to distance or obstruction, each wireless
device is capable of locating an alternate route through an additional wireless device to communicate with
the designated device. This innovative technology is designed to create a robust network that automatically
routes around congestion and line-of-sight obstacles while improving throughput as subscriber device
density increases.
The radio module is housed in a black ABS box mounted inside of the CX stainless steel enclosure. The
standard package includes two PCAs mounted inside the black ABS box (radio PCA and Smart battery
charging PCA), 5 dB antenna, and a protective antenna cover. The battery PCA includes circuitry to safely
recharge the battery from a 24VDC input and a fuel gauge circuit to monitor the charge remaining in the
battery.
The radio PCA includes a 2.4Ghz radio and a rotary switch for setting the RF channel of the system (Figure
2). Use a small screwdriver to rotate the switch until the arrow points to the desired RF channel number (16
channels available, 0h-Fh).
NOTE
All devices within the network must be on the same RF channel to operate correctly.
Each radio module is required to have a unique address. These addresses typically start at 01h and continue
sequentially for each SmartWireless CX in the gas detection system. The radio PCA includes a pair of
rotary switches to set this address (Figure 2).
NOTE
The switch for the most significant digit (MSD) is on the right and the least significant digit
(LSD) is on the left.

5.4 Servicing Risks and Verification of Safe State after Servicing
While performing any of the above-mention user-authorized service activities, proper caution shall be used
to avoid safety risks.
The first protective measure and mandatory requirement is that the CX Sensor Station must be relocated to
a non-hazardous area while performing these functions.
The second protective measure is to make sure the power switch is turned OFF while opening the enclosure
and addressing internal components.
The third protective measure is to use static protection while touching any internal components within the
controller enclosure.
The fourth protective measure is to follow these instructions properly and secure the hinged enclosure
cover fully closed before returning unit to the hazardous area.
Once all servicing has been completed turn power ON and verify that all configured gas sensors are reading
the correct value and also verify that the battery charge level is correct. Once verified, it is safe to return
the unit to active usage.

6. Troubleshooting Guide
Sensor COMM Error
Verify all SmartWireless® CXT devices have a unique Modbus ID number.
Verify the Sensor Input PCA and Relay PCA Modbus address are set correctly
Verify the Radio Module Modbus address is set correctly
Sensor Fault
Verify if sensor displays any fault. If so, follow sensor trouble shooting notes.
Verify if sensor cell needs replacement.
Low Battery
Attach external battery charger
Verify solar panel (if used) is oriented correctly
Poor Link Quality
Verify antenna is securely attached to all devices.
Verify obstructions are eliminated or minimized between SmartWireless® CXT devices and
controller or other CXT devices.
Sentinel CX
Slow Gas Response
Some delay in gas response is normal if the network update rate is greater than zero. To increase
response time, reduce the update rate. Reducing the update rate will reduce the battery life for
devices.
SmartWireless® CXT not found during controller Auto Configure
Verify CXT device set to correct RF Channel
Verify Radio Module has correct Modbus address
Verify the Sensor Input PCA and Relay PCA Modbus address are set correctly
Verify a proper mA load is present on sensor input. Sensor inputs are not detected unless the mA
input is greater than 1.9mA.
